Form 16

1. You are right, form 16 cannot be issued in the mid of the year
2. But you can issue IT computation for the respective period
3. This statement would include month-wise earnings/deductions

Thanks Poornima for your reply can you please send me a format for IT computation.

Similar to the one in the link. You need to make modifications to suit the relevant AY.
